sassy I think that is pretty close to right. For me this is my rule.
bodyweight X 2g ( of protein) = total g of protein per day / 6 (meals per day)
so say i'm 200lbs, that is 400g of protein (max) per day, divide by 6, is going to get you approximately 67g of protein at one meal. That might be a little on the high side but with someone with a regular workout routine I think it will be real close.
